Brief Summary
Irritable bowel syndrome (IBS) is a common functional bowel disorder that imposes a considerable burden on health-related quality of life (QOL) worldwide. Irritable Bowel Syndrome (IBS) is a common digestive disorder affecting 7-21% of the general population. IBS with predominant constipation (IBS-C) is a subtype of IBS that accounts for more than a third of the IBS diagnosed. The study Sponsor, Devintec SAGL, presents GA-AT0119, which acts by forming a mechanical barrier on the intestinal mucosa thanks to xyloglucan and pea proteins avoiding the increased intestinal permeability, bacterial invasion to intestinal tissues, and subsequent intestinal inflammation. The formulation of GA-AT0119 is completed with chia seed powder which provides a laxative effect by retaining water in the intestine increasing stool bulk and accelerating fecal transit. There is increasing evidence that the pathophysiology of IBS is multifaceted involving mucosal inflammation, visceral hypersensitivity, microbial dysbiosis, dietary factors, and altered intestinal permeability (IP). Several studies have shown increased intestinal permeability in patients with irritable bowel syndrome. Serum zonulin, a biomarker of impaired increased permeability, is increased in patients' constipation-predominant irritable bowel syndrome compared to a healthy population and the levels are comparable to celiac disease.

Outcome Measures
Primary Outcomes (12)
Change from baseline in Subjective Symptom Improvement assessed through Likert scale (Discomfort, Bloating Abdominal Pain) at day 7, 15, 28, 56, 84,114,144
The clinical symptoms that are going to be assessed through the 7 point Likert Scale are: Bloating, Discomfort, abdominal pain. Likert scale - level of acceptability: 1. \- Totally unacceptable 2. \- Unacceptable 3. \- Slightly unacceptable 4. \- Neutral 5. \- Slightly acceptable 6. \- Acceptable 7. \- Perfectly Acceptable
144 days
Change from baseline in BMI assessed at Day 7,15, 28, 56,84
The BMI will be evaluated
84 days
Change from baseline in stool consistency will be assessed at Day 0, 7, 15, 28, 56, 84, 114, 144, through the Bristol Stool Scale.
Type of stool will be assessed according to the Bristol Stool Chart ((Stool Type 1 - severe constipation, Stool Type 2 - mild constipation, Stool Type 3 - normal, Stool Type 4 - normal, Stool Type 5 - lacking fiber, Stool Type 6 - mild diarrhea, Stool Type 6 - severe diarrhea)
144 days
Change from baseline score in IBS-QoL questionnaire (Information Sheet on the Irritable Bowel Syndrome - Quality of Life Measure) at Day 7, 15, Day 28 and Day 56, Day 84, Day 114, Day 144
Patients will respond to the IBS-QoL questionnaire. The individual responses to the 34 items are summed and averaged for a total score and then transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS specific quality of life.
144 days
Change of Sickness Impact Profile score from Baseline to Day 28 and day 56, day 84, Day 114, Day 144
The generic health status, the physical, mental and social aspects of health-related functioning and behavior aspectes will be measred through - The Sickness Impact Profile (All the items are scored dichotomously (no=0, yes=1); The items reported as "yes" are used to calculate the scores; higher scores indicate more health-related behavioral problems)
144 days
Change from Baseline (Day 0) to Day 7, 15, 28, 56 in Zonuline test
Serum Zonuline test will be performed
56 days
Change from Baseline Day 0 to Day 7 in the VAS-IBS questionnaire (Visual Analogue Scale for Irritable Bowel Syndrome) evaluated by Patient Journal Daily on each symptom
The VAS-IBS will be assessed through the Patient Journal. In the VAS-IBS the patients record the overall severity of each item on a 100 points line (very severe discomfort = 0 to no discomfort at all = 100).
7 days
Change from Baseline Day 0 to Day 7 in the VAS-IBS questionnaire (The Visual Analogue Scale for Irritable Bowel Syndrome) evaluated by Investigator at Day 15, Day 28 and Day 56, Day 84, Day 114, Day 144
The Investigator will assess the symptoms in patients suffering from IBS - using the Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS) questionnaire. In the VAS-IBS the patients record the overall severity of each item on a 100 points line (very severe discomfort = 0 to no discomfort at all = 100).
144 days
Number of AE occurrence
Adverse events will be monitored during all the visits till the end of the study and reported accordingly
144 days
% of participants with withdrawal due to AE
Withdrawal due to adverse events will be monitored during all the visits till the end of the study and reported accordingly.
144 days
Change from baseline in waist circumference assessed at Day 7,15, 28, 56,84
The waist circumference will be evaluated
84 days
Change from baseline in number of stools will be assessed at Day 0, 7, 15, 28, 56, 84, 114, 144
Number of stools will be assessed
144 days
